A root canal is a common dental procedure use to treat infection or damage to the pulp tissue. Over time, the structure of treated teeth weakens, and if crowns do not protect them, they are at an increased risk of fracture. Dental crowns preserve the tooth’s structure, prevent breakage, and enhance aesthetics.
However, even a crowned tooth can develop an infection, requiring a root canal. The good news is that a root canal can be perform through an existing crown without needing removal.
Here’s a step-by-step breakdown of how to do a root canal through a crown and what to expect.
Root Canal – The Procedure
The root canal treatment is done in the following steps –
- The patient is give local anesthesia or a local anesthetic in combination with a sedative. This is administration to keep the patient pain-free and comfortable during the procedure.
- A rubber dam is place to prevent any contamination from happening.
- A hole is drill in the tooth to gain access to the pulp chamber
- The infected tooth material is remove.
- Using special filing instruments, the pulp chamber, along with the root canals, are clean and shape.
- The chamber is constantly irrigate to prevent any debris from accumulating.
- X-rays are taken to determine if the shaping is done sufficiently.
- A rubbery inert material is condense into the canals.
- A permanent filling is done over the rubbery material.
- The tooth is topp with a dental crown to retain its structural integrity.
If the procedure is carry out in two sittings, a temporary filling is place until the second appointment. The dentist might also add medication to treat any remaining infection.
How Long Does A Root Canal Take In One Visit?
The length of the root canal process depends on the tooth to be treated and the extent of the infection.
- Molars (Back Teeth): 90 minutes per visit (due to multiple roots).
- Premolars (Between Front & Back Teeth): Around 60 minutes.
- Incisors & Canines (Front Teeth): Up to 45 minutes.
If a crown placement is need, an additional appointment of about an hour is require after the treated tooth has healed.
The placement of a dental crown takes additional time. It is done in a separate appointment and takes about an hour for the final set and placement. Crowns are place only once the treated tooth has had a chance to heal.
What Type Of Dentist Performs Root Canals?
A general dentist can perform root canals, but an endodontist is a specialist who specializes in these treatments.
Endodontists receive the same basic education as general dentists. However, they undergo additional studies and endodontics training, enhancing their skills and clinical expertise in root canal treatment.
Indications of Getting a Root Canal Crown:
A crown after a root canal is usually require for the following reasons:
- Tooth Weakness and Structural Damage: With the removal of pulp, the tooth loses its nutritional supply and becomes weak, requiring a crown for reinforcement.
- Location of The Tooth: Molars and premolars, which endure high biting forces, need crowns for additional support.
- Prevention of Fracture and Infection: Crowns are crucial for root canal treat teeth to prevent filling fractures and subsequent infections that may arise from leaks.
Why Would a Tooth with a Crown Need a Root Canal?
A tooth that is crown can develop a dental infection over time due to the infiltration of bacteria below the crown. Even with a dental crown, infections can occur due to:
- Decay Beneath the Crown: Poorly fitted crowns can trap bacteria, leading to infections.
- Pulp Inflammation or Necrosis: Deep fillings or trauma may damage the pulp.
- Abscess Formation: Prolonged infection can lead to painful swelling and abscesses.
- Reinfection of a Treated Tooth: Missed canals or incomplete fillings from prior treatments can cause re-infection.
How Can A Root Canal Be Done Through A Crown?
Doing a root canal through a crown is similar to the traditional method, except the crown limits the view and assessment of the chamber.
Step-by-Step Process of a Root Canal Through a Crown
- Diagnosis & Treatment Planning: X-rays and oral exams determine the extent of infection.
- Accessing the Root Canal: A small hole is drill through the crown.
- Cleaning & Disinfection: Infect tissue is remove, and canals are flush with disinfecting solutions.
- Filling & Sealing: Canals are seal with gutta-percha to prevent further infection.
- Restoring the Crown: The drill area is fill and sealed with a durable dental material.
Is there any Difference Between a Regular Canal and a Root Canal Crown?
Regular crowns and root canal crowns are made from the same materials but differ in their purpose, structure, and preparation.
- Purpose: A regular crown is not necessarily placed to restore the treated tooth. It can be place on the non-RCT tooth to correct cosmetic issues such as discolorations or abnormal size and shape of the teeth. Root canal crowns are place to protect the treat tooth from breakage.
- Tooth Structure and Integrity: Regular crowns can be placed to support a structurally sound tooth with intact natural structure. However, RCT-treated teeth become brittle over time and need crowns for support.
- Preparation: Regular crowns need minimal tooth alteration, while root canal-treated teeth may need a post-and-core buildup.
- Choice of Material: Regular crowns are place depending on the requirement and concern of the teeth, whereas high-strength materials are often prefer for root canal crowns.
Root Canal Recovery Time
Patients who undergo a root canal experience sensitivity and mild pain for about 2-3 days after the procedure. The pain is manageable with over-the-counter analgesics and usually subsides on its own.
There are no specific things to avoid after a root canal except smoking. Eat a soft diet and avoid foods and drinks with extreme temperatures.
After a dental crown, the patient can return to their regular eating habits. However, care must be maintain to follow proper oral hygiene.
